Figure 13 is an enlarged detail of a portion of our machine.

We have illustrated in the drawings our automatic tobacco scrap measuring and rolling machine which is provided with a scrap I receiving compartment A, an elevating mechanism B, a spreadin mechanism C, a rolling mechanism D. These parts are connected together in a manner so as to be operated automatically to weigh a predeter- 'mined amount of tobacco scrap after it has been elevated and spread out so that the scrap can be discharged into the rolling mechanism which is operated by hand to roll the scrap in bunches with a binder about the same.

The receiving compartment A is provided with an angle iron frame 10, side walls 11 and a screen bottom 12.

An elevator mechanism B extends into the compartment A with its lower end 13 in close proximity to the screen bottom 12 and with the upper end 14 extending up from the compartment A and supported by the side por- V tions 15 which are formed as a part of the sides 11 and project above the same. The lowor end 18 of the elevator mechanism B is ad justably positioned in the slot 18 formed in the sides 11 of the compartment A. An endless carrier belt 17 is provided for the elevator B and by means of the wire shelves 18 which are supported by the plates 19 to the belt 17, the tobacco scrap is elevated on the shelves 18 in the operation of the elevator mechanism B. By means of a'suitable brush 20 positioned near the top of the compartment A, the projecting or surplus portion of the tobacco scrap picked up by the conveyor is brushed off of the shelves 18 as they pass by the brush 20. This permits practically a uniform amount of scrap to be picked up by the shelves 18. p

The screen bottom 12 permits the fine, screenings in the tobacco scrap to drop through from the compartment A to the floor. Vi e also provide a screening member 21 in the col partment A which extends at an angle toward the end 13 of the conveyor, thereby providing a long slanting wall which has a tendency to screen the-scrap as it is poured into the compartment A. This permits the fine material to be sifted out of the scrap quite completely, nevertheless, the lifting shelves 18 are of an open wire construction as illus trated in Figure 3 so that any little fine material drop through the same and not be elevated up to the spreading mechanism C.

When the tobacco scrap is lifted by the shelves 118 up to the top of the conveyor 14 it is adapted to be dumped against the adjustable and sliding shelf 28. This shelf is positioned between the side walls 15. The shel 23 is formed with a short portion 2 1 which is hinged. at 25 to the side walls. The plate portion 26 of the shelf 23 is adapted to extend beneath the inturned lips 2'? formed on the short portion 24 and freely disposedbeneatli the lips 27 so that the plate portion 26 can slide back and forth. A pintle member 28 is secured to the plate 26 and, is adapted to s bile bear against bracket guide 29, while a spring 80 holds the pintle against the bracket 29, and a second spring 31 pulls the pintle 28 toward the hinging point 25 of the short member 2 The free end 32 of the plate 26 is adapted to bear slightly against the upper end 14 of the conveyor B. A cam member 38 is positioned above the pintle 28 so that the pintle 28 may be guided up over the cam when the free end 82 of the shelf 23 is forced downward by the shelves 18 as they pass by the shelf 23. This adjustable shelf 23 receives the tobacco scrap as it is discharged on the same and the shelf 23 is adapted to slide with the pintle member 28 up over the cam 38, thus providing an adjustable receiving shelf for the tobacco scrap as it is dumped from the conveyor B at the top 14.

As the tobacco scrap is dumped on to the plate 28 it is adapted to slide down the chute or channel 35 and on to the spreading roller The spreading roller 36 is rotated in the direction of the arrow illustrated in Figure 11 and receives the tobacco scrap in the pocket portion 37 formed by the lower part of the chute 35 and the surface of the spreading roller 36. The roller 36 is of any suitable material having a textile cover or other suitable covering material over the same and adapted to pick up the tobacco scrap from the pocket portion 87 and carry it over the pe riphery of the roller and dump it on to the conveyor 88. The conveyor 38 is operated in the direction of the arrow toward the front of the frame E which supports the weighing mechanism of our machine.

The/roller 36 is operated by the belt 40 from the shaft 41 and the shaft 41 is operated by the belt 12 which EXtGIlClS from the shaft 43 at the upper end 14- of the conveyor B. The shaft A3 is operated by the belt A l from the shaft 45 which shaft is operated by the belt 16 from the motor L7. The shaft A5 is the main drive shaft of our machine and the belt i6 is adapted to extend over the pulley 48 carried by this shaft, which is illustrated in Figure 6.

The belt .38 extends along the frame E to the front of the same and is adapted to carry the tobacco scrap into the weighing cup F. The belt 38 extends beneath the spreading roll 36. As the tobacco scrap is dropped into the pocket 37 and against the spreading roll 236i; is piclred up and carried over on the belt 38 which is operating at the same time that the sp ling roll 36 is in operation. I v m "r r 1111s spreads the tobacco sci ap out and has a tei'idency to e tend it in parallel and longitudinal relation sothat when it is dropped into the weighing cup F the s rap is inclined to lie in a stacked longitudinal relation, one piece to the other. The weighing cup is formed with a hinged front portion 50 which is pivoted at 51 to the back portion The portion 50 is counterbalanced at 53 so as to hold the f no edge 54 of the bottom portion normally in closed position. The weighing mechanism H is supported by the frame E which includes the arms 55 which support the cup F between the frame E and which are adapted to rest against the balancingblocks while the free end of the arms 55 are joined together by the cross member 57 and are adapted to adjustably carry the weight 58 on the rod 59 which is attached. to the cross member 57. The weighing mechanism for the cup F is also provided with a line adustment for balancing the cup F which includes the rod 60 which is adapted to rest upon the balancing block 61 and which is provided with an adju'stable weight 62 on its free end, while the other end is connected by the cross member 63 to the members The rod 60 is provided with an arm 64 depending from the same, see Figure 11, which is adapted to provide the connecting arm for the electric switch The electric switch ('35 is adjustably connected to the plate-66 upon which the balancing blocks 56 and 61 are positioned. The s vitch (i5 is located directly below the rod 60 at the front end of the The function of tl'iis'switch together with the con necting circuit will be hereinafter more fully described. I

The weighing cup F is adapted to be operatec to cause the hinged portion 50 to be opened as illustrated in Figure 10, when the rollingmechanism D is operated into backward position. The rolling mechanism D is provided with a frame 68 which is supported by the forwardly projecting portion 69 of the frame 70 of our machine, directly in front of the frame E which carries the spreading and weighing machinsm. The rolling mechanism is formed with an operating arm 71 which is pivotally secured at 1 2 at the top of the frame 68 and this operati arm is connected to the cam member 7 wh, it is adapted to operate the lever to cause the same to move in a backward direction, illustrated in dotted outline in Figure 11, in the operation of the rolling mechan' The forward movement of the operating arm 71 is illustrated indotted outline in Figure 11, while the different positions of the cam is also illustrated in dotted outline in this figure. The lever 74 is pivoted at 75, while the upper end '76 of the same is adapted to operate in the slot 77 formed in the cam 78. he le c 71 is provided with pin 78 which peratcs in the slot 79 of the cam 72-3.

The lower of the lever 74 is conne ted at 80 to one end of the rolling belt 81, while the other end of the rolling belt is held boneath the clamp 82 on the front of the table 83 of the rolling mechanism D. The lower free end 84 of the arm 71 is adapted to extend beneath the rolling belt 81 in backward position, and the belt 81 is provided with suflicient slack so that when the operating arm 71 is in backward position, or as illustrated in full lin s, the belt 81 is adapted to extend and drop down into a recess h the table 83 o form a pocket 85 in the beltSl. The lever 71 is formed with a hand engaging portion 86 which permits the lever 71 to be engaged by hand and operated to pull it into forward position as illustrated in dotted outline in Figure 11.

In the operation of the mechanism D the iandle 86 is engaged and the lever 71 pulled forward into the dott d position illustrated. As the lever 71 is operated in this manner the belt 81. is adapted to be drawn over the free end 8 1: of the lever '71 and the cam 73 is operated into position to cause the lever 74. to move backward into the position illustrated in dotted outline taking up the slack of the belt 81 and rollin the contents of the tobacco scrap which has been dropped into the poclret 85 between the sides of the rolling belt 81 and to roll he same into the desired shape. A tobacco-loaf binder is laid down and spread out upon the belt 81 when the lever 71 is in backward position so that when the lever 71 is pulled forward the contents of the pocket 85 is rolled into the binder in a smooth and finished manner so that the tobacco scrap completely bound in aroll with the binder about the same time the free end 84 of the lever 71 reaches the forward end of the table 83.

The cup F connected by a chute 88 with the pocket 85 so that when the cup F is opened the contents of t 1e same drops down the chute 88 and into the pool 85. The frame 68 of the rolling mocha D is provided with a support or bra t 89 and plate 90 which support the operating rod 91, illustrated in Figure 10. The operating rod 91 is held in position b the coil spring 92 with the free end 93 engaging against therel-easing dog 94. This dog is pivoted at 95 to the frame E directly adjacent tr e weighing cup F and in back of the same. means of a bracket 96 a trigger member 97 is supported to the frame E and is adapted to be held against the coil spring 98 when the dog 94 is in the position illustrated in Figure 10 with. the

latch 9 held in the position il ustrated in full lines. The latch 99 is pivoted at 100 to the trigger rod 97 and is caused to move in upright posi -on as illustrated by the adjustable arm 101. T e latch 99 is adapted to engage the lower f of the portion 50 of the cup F t e same into the position illustrated .l outline in Eigure 10,

'1 is moved into backwarc position with one bar 102 d by the lever '71 engaging a ainst the 103 of the rod 91. Thus when the lever 71 is moved into backward posi"ion the end 93 the rod 91 will strike 2. st the dog 91- and release the trig er 1'00. 97 and cause the latch 99 to snap against the lower edge of the cup F and quickly swing the portion 50 into open position, dumping the contents of scrap into the chute'88 which slides in its approximate stacked condition into the recess 85 in the belt 81. The counterwe' t 53 on the portion 50 of the cup F causes it to assume its closed position as soon as the cup F is emptied. The trigger rod 97 is moved back into normal position with the latch 99 engaging the same, as illustrated in full lines in Figure 10, by means of the rod 101 which is formed with a depending end carrying the roller 105 which is engaged by the lever 74 as it moves in its backward position, as illustrated in dot-ted outline in Fi are 10.

When the trigger rod 9'? is released by the rod 91 which ra ses the dog 91, the spring 98 shoots thelatch 99 against the lower edge of the portion 50 of the cup F to open it. When L a th e tion as illustrated in dotted outline in Figure 10 it rotates on its pivot poin 100 to drop into the position illustrated so that when it is pushed back by the rods 101 in the backward movement of the rod 71 it will clear the bottom of the cup F, but as the lower edge of the latch strikes the arm 101 the latch is raised into operating position as illustrated in Figure 10 in full lines thus setting the latch automatically into operative position to open the cup F quickly when the trigger 97 is released. In the operation of the machine, which will be hereinafter described, as the cup F is filled and the contents of the same is wanted by the operator on the table 93, the contents of the cup is eleased automatically and the operating parts of our machine are adapted to begintofunction him This operation will be hereinafter described. 7

' The countershaft 15 is supported by the frame below the frame E by the bearing members 108. This shaft is divided into portions 109, 110 and 111, all of which portions extend coaxial through the bearings 108. The portion 109 is adapted to carry the friction clutch member 112 which is keyed to the shaft portion 109 so as to rotate with the same. An engaging plate 118 which is adapted to engage the clutch member 112 is keyed to the shaft portion 110 and adapted to rotate with this portion of the shaft. '11 stud 11 1 is formed on the end of the shaft 109 adjacent the end of the shaft 110 which is adapted to project into a recess formed in the shaft 110 and by means of a coil spring 115 within the recess in the shaft 110, the plate member of the clutch G, formed by the members 112 and 113, is at times held out of engagement with the member 112. The portion 111 of the shaft 45 does not rotate and a suitable ball thrust bearing 116 is interposed between the end of this shaft and the end of the shaft 110 adjacent the same. We also provide a'ball thrust bearing 117 on the outer end of the shaft portion 109.

The clutch G is adapted to be operated by the solenoid 118 which is connected by the lever 119 to the portion 111 of the shaft 15. VJ hen the solenoid 118 is operated it will force the portion 111 against the portion 110, thereby causing the plate 113 to engage the clutch me nber 112. The motor 17 i adapted to operate the belt e'6 which extends over the pulleys 48 carried by the countershaft 45 and which is keyed to the portion 110 of the same. Normally the motor 17 operates the portion 110 of the shaft to continue to rotate the same when the motor is turned on and not until the solenoid 118 is in operation do the other parts of our tobacco scrap machine function.

Our machine is provided with circuitbreaking solenoid 120 which is positioned back of the countershaft 15 and is only partly illustrated in the drawings in Figure 1. To clearly illustrate the wiring diagram and electrical operation of the parts in our chine we have illustrated diagrammatically in Figure 12 the wiring diagram with the solenoids and electrical switches. In this illustration the line current comes in on the wire 121 and the wire 122. The motor 47 is connected by the lead 123 and the wire 124 which connects with the hand switch 125. The hand switch then connects back to the line through the wire 121. Thus when the switch 125 is closed the motor 417 will be oper ated from the line current through the leads 121 and 122 through the leads 128 and 124:. Normally the motor 17 is operating continuously when the machine is turned on and the switch 125 is closed. The solenoid 118 is connected with the lead 122 by means of the lead 126 the solenoid 118 with the circuit breaker solenoid through the switch 127 and from the switch 127 the lead 128 connects the solenoid 118 with the switch 125 and back to the line wire 121. This completes the circuit so that the solenoid 118 is in operation to hold the clutch G operating, thereby rotating the countershaft 15 and operating the pulley 129 which is-connected by the belt 14: to the shaft 43. Thus when the clutch G is closed the conveyor B is adapted to elevate the scrap from the compartment A and the spreader is operated through the belt 42 and the short belt i0, while the belt 38 is also in operation and the scrap is adapted to be carried to the cup F. When the ch F has been filled with the amount of scrap for which it has been set to receive, that is the predetermined amount gauged by the scale mechanism H, it is adapted to close the switch 65, thus closing the circuit to the break solenoid 120 wi icl opens the switch 127 and breaks the circuit in the solenoid 118, releasing the clutch G and immediately stopping the elevating me -chi nism E ant the spreading mechanism which is adapted to fill the cup F. This construction provides an electrical automatic means for weighing a predetermined amount of tobacco scrap into the cup F in the operation of our machine. The solenoid 120 is connected to t ie line 121 through the switch 125 by the leads 130 and 131 through the switch and the lead 132 connects with the line 122. Our automatic tobacco scrap measuring machine is adapted to operate electrically so that the motor s7 will automatically operate to cause the conveyor mechanism B to bring the tobacco scrap to the spreading mechanism C and the spreading mechanism C automatically fills the weighing cup F, whereupon the weighing cup automatically closes the switch 65 which automatically and instantly stops the function of the solenoid 118, stopping the clutch G and thus stopping the spiuading mechanism from the compartm at A to the cup F. The cup F holds the tobacco scrap in virtually stacked relation with the scrap extending comparatively longitudinally and parallel to each other until it is desired for use.

he operator of our machine is positioned in front of the rolling mechanism D and by engaging the handle 86 the lever 71 is drawn forward which rolls the tobacco scrap which has been discharged into the pocket 85 into a binoer which has been placed on the belt 81 on the table 83. The spreading and stacking of the tobacco scrap as hereafter described forms important feature of our invention as it lays the particles of scrap in longitudinal relation and permits the same to be rolled in the binder without wrinkling, buckling or tearing the same, thereby permitting the operator of our machine to turn out better work more rapidly and with much more ease of operation than has ever been done heretofore in so far as we know.

We provide our rolling mechanism D with a guard member 135 which is pivoted at 136 and is formed of an angular nature having the shelf portion 137 which normally projects back under the chute 88 as clearly illustrated in Figure 11. In operating the rolling mechanism the handle 86 is engaged to pull the lever 71 forward to roll the scrap in the pocket 85 the slack portion 138 of the belt 81 is carried backward by the arm 74 and the guard 135 to the free end 8% of the lever 71 until it engages with the corner 139 of the table 80 so that the shelf 137 of the guard he opening between the end of the :l the table 83 when the lever 71 pi, forward and the scrap is being rolled between the sides of the belt 81. Thus the table fo a smooth surface on which the f portion is adapted to rest and the b t is adapteifl to slide in a flat smooth state over the same while the free end 84 pushes he guard bacli into normal position, as .lius ted in Figure 11. This performs a important function in our invention in no rolling mechanism as it causes the belt to drop automatically into the pocket 85 o" sh pe to form the pocket 85 at the back the table 83. Without this guard 135 the t 81 would buckle and would not automatical-1* form itself into the pocket shape 85 as trated in Figure 11. This pocket receives the tobacco scrap from the cup F and as the aoclret is formed by the drop in the belt 81 readily apprehended the importance of orming of this pocket to receive the scrap w'thout the attention of the operator so that the ooerator may lay the binder on the belt and attention to having the binder smooth and in position ready to receive the c between the sides of the belt 81 when. the lever 71 is pulled forward.

31s the operator completes the rolling operation by pulling the lever 71 forward, the

Yon illustrated in full lines in Figure 11, and in this operation the lever 71 automatically trips the trigger rod 97 which automatically opens the cup F and discharges the tobacco scrap in the cup F which has been properly weighed, down the chute 88 into the pocket 85. The moment the cup F has been emptied the switch 65 is opened and the circuit through the solenoid 118 is simultaneously closed by the closing of the switch 127, and immediately automatically the elevating spreading mechanism of our machine starts t= operate in a manner to again fill the cup F with tobacco scrap. This operation is ontinued so that the moment the cup F is lied the mechanism is automatically stopped not until the operator releases the contents of the cup I does the filling and spreading mechanism start in operation. This pernits the operator to control the operation of our machine through the rolling mechanism and to operate the same just as rapidly as desired.

The operation of the rolling mechanism is very simple and ooes not require skilled labor and as all the mechanism of elevating and spreading and filling the scrap to the weighing cup F is automatic, the operator er 71 is then moved baclnvard into the po-' can be secured with our machine than has ever been accomplished heretofore with any otl device that we lznow of.

The electrical operation of our automatic scrap weighing and rolling machine permits the parts to function quickly and accurately so that the amount of scrap rolled into each binder ispractically the same, thereby giving a uniformbody for a scale, a feature which is very important in a machine of this nature. The screening of the scrap, the open shelves, th spreader roller, all provide means which function together to give the desired operaion of our machin The double adjustment in the weighing mechanism is of importance as it is clearly evident that the weighing mechanism crates the starting and stopping of the filling of the cup of our machine, thus gauging the exact amount of scrap which is rolled in each binder. Further, the rolling mechanism functions with the weighing cup and mechanism to start and stop the machine at the proper intervals. Our machine permits practically perfect work to be accomplished without a skilled operator, thus decreasing the cost of manufacture and also increasing the speed in pro duction.

In accordance with the patent statutes we have described the principal features of our machine and the details of construction, and while we have illustrated a particular forma tion and design in the drawings, we wish to have it understood that the same is only suggestive of a means of carrying out our invention, and that the same may be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
